Television and Home Theater

I have a Mitsubishi WD-73732 dlp tv that has a blinking green light that keeps turning off.  I have replaced the bulb with OEM part and still have same issue.  It appears as though I have a similar problem as other Mitsubishi sets.  Does any one have a service manual or a direction I can head in to fix this?

Thanks,

Jeff

My samsung hln507 started with picture would go off and still have sound. I would have to unplug to get it off then plug back it  back in then it would do it again in 10-15 min. Now it lights comes on for 20 sec then off with the three blimking lights. It will not restart it's self like it does when the bulb goes bad. I replaced the bulb 8 months ago and the color wheel 2 months ago. Im lost and don't know were to start this time. thanks

I just got thru reviewing the DM Capacitor Repair guide hoping it might shed some light on my brightness issue. But there was no mention, I pulled the DM and mine shows no signs of bad caps and my TV starts normally, no blinking light problems. However, the TV seems to have a mind of its own regarding brightness. It seems to fluctuate levels of brightness all on its own, going from a normal picture to gradual fades to fast fades. I never loose the picture to complete darkness, just to very low brightness levels.
